yes, I have now tested the exact or similar same boot-environment as Matthew:
Having u-boot as the payload sitting on the pxe-server instead of SD-card,
As a complete diskless boot by configuring the eeprom as pxe-bootable.
It’s an issue in old friend bcm2711-rpi-4-b.dtb :
using newer versions of it fail to boot(stopping at net0: cannot set rx. filters (status=3)
/)
 while older versions ends up in the 
Interrupt-loop(genet0: gen_intr2).

I could successfully netboot from SD-card some weeks ago, so this seems not necessarily 
an issue with your driver. It only loops when u-boot is placed on the pxe-server.
IIRC any netboot seemed to depend on the right combination of firmware/msdos-partition 
and the corresponding fbsd-version .
